Gas sending unit OHMS?
 

Anyone know what OHMS range a gas tank sending unit would be (stock) in a 66 GMC pickup? 0-90 ohms, 70-10ohms, 30-180ohms or 240-33ohms? I am getting a new fuel guage but I want to make sure I am getting the right one.

Worst case I suppose I could pull it and measure the ohms based on the leaver being full and empty but I would like to avoid doing that if possible.

Thanks a bunch.

Why not do the ohm check yourself? I wouldn't want to guess at something like that. It is a little hassle getting the sender out of the tank but at least I would know for sure.

I'm not positive, but, I thought all GM senders are 0-90.


PS:
Did a little more checking and found out,
Pre 1965 0-30 ohms, post 1965 0-90 ohms.

I agree, but this only applies if you are getting a stock GM replacement gauge. If you are getting an aftermarket gauge, it might differ by manufacturer but it should be marked and you can match it to your stock sender.

Thanks for the help guys. Much appreciated.
